Did you try to right click on the file, then click on "save target as..."? Sometimes that is the best way to open a file, especially the .pdf files. One thing that helped me was to update my Adobe Reader to 7.0--haven't had very many problems since doing that. Here's a link to the Adobe site for the download:

HTH!
If neither of these work, PM me your e-mail addy and I'll send you the file!
